1. Lubricants on the base of calcium complex sulfonate with modified thickener structure Andrey Yasnovsky, Technical Director, TOTAL Lubrifiants Russia and CIS

2. Requirements of the European market concerning the main types of lubricants
Resistance to high temperatures
Super high pressure
Corrosion protection
Water resistance
Self-recovery
Mechanical stability and resistance to shift
Good pumpability (providing the pressure in the centralised lubricant feed system is no lower than 60 bar)
Cost requirements: the average cost of lubricant with a Ca thickener does not exceed 10% - 25% of that of the most widespread Li thickener, even though it has higher operating attributes

3. Thickener: basis of the technology
(R - SO3)2Ca + CaCO3 (amorphous phase) + promoting agent + polar solvent  (R -SO3)2Ca CaCO3
Conversion to crystalline (calcite form). The alternate crystal structure, (vaterite) has a needle structure and is unstable and of no value as a lube additive.
The process of slow homogenisation is very important for the future stable operation of the lubricant (TOTAL Ceran)

4. Thickener – base (standard)
Calcium sulphonate (composite)

5. Vaterite Calcite Possible forms of CaCO3
The secret of the thickener – stable conditions of homogenisation, observance of the technology
Vaterite
A poor barrier for water
Unstable system
Possible forms of CaCO3
Stable system
A good barrier for water
Calcite

6. New technologies: the additive is a part of the thickener
Additives and admixtures
Carbonate Ca
Size: нм Ca Ca Ca Ca
Organic chains Ca Ca Ca Ca Ca Ca
